1 Claim.

The `invention relates to valves and more especially to duplex lift valves for pumps or the like. The primary object of the invention is the provision of a valve of this character, wherein the construction of the same enables theclosing of such valve vwithout; any noisy slap and when closed will be leak-proof.

Another object of the invention is the provision of a valve of this character, wherein ay perfect seating of the same is assured due to the peculiar baille arrangement present lin the structure.

A further object of the inventionfis the pro- 'vislon of a valve of this character, wherein repairs and adjustments may be eifected with ease and dispatch.

A still further object of the invention is the provision of a valve of this character, wherein-l the construction thereof permits the use of the same with compressors, ordinary water pumps, being effective as a check valve, vacuum breaker and is usable on oil pumps or most any other types of machines where a valve may be required.

A still further. object ofthe invention is the provision of a valve of this character, which is extremely simple in construction, thoroughly reliable and efclent in operation, strong, durable, quick acting, and inexpensive to manufacture and install.

With these and other objects in view the inventlon consists in the features of construction,

combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing: Figure 1 is a fragmentary top plan view of the valve assembly constructed in accordance with the invention and parts thereof being broken away for illustrative purposes.

Figure 2 is an enlarged sectional View taken on the line 2-2 of Figure 1 looking in the direc- 'tion of the arrows.

Figure 3 isa view similar to Figure 2 showing the parts-in an adjusted or changed position.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

body I8, and when the latter is seated on the Referring to the drawingin detail, A deslgl nates generally the valve assembly constructed ln accordance with the invention and comprises a ring member I0, the outer annulus Il .of which through radial spokes I2 is joined with a central hub I3 provided with a bolt hole I4 having the threads I5 for the engagement therewith of a Slidably tting the bolt I6 is the central sleeve I1 of a disk valve body'I8. The sleeve |1,i s formed at its outer end with a stop flange I8. Slidable onA the sleeve Il is the central-sleeve 2lil of a second disk valve body 2|. The sleeve 28 at its outer end is formed with astop ange 22 cooperating with/the ange I8 under the assembly of the sleeves Il and 20, both'being detachably engaged with the valve'bodies' |8 and 2|, respectively. l

The valve body I8 is of greater size than the valve body 2| and the sleeve of said body I8 is longer than the sleeve 20 of the body 2|, so

that the said valve body 2| will Shave a determinedmovement toward and from the valve body I8, while the latter will have a determined movement toward and away from the coupling ring IIIl against which it is adapted to `be seated in the vworking of the valve assembly A. The

` valve body I8 is adapted to be seated against the -valve body 2| in the working of the valve assembly A. 4

In the annulus II of the member I8 and in the hub I3 of the vlatter are formed inner and outer concentrically disposed annular substantially V-shaped grooves 23 which' accommodate correspondingly shaped concentrically arranged inner and outer annular ribs forming baliles l24 when the valve body I8 is seated upon the member I0.

., These .baiiles 24 are on the under or bottom face 25 of vthe valve body I8 and the grooves 23 member III the valve assembly A is completely closed.

The bolt I6 is of a length to have its head 38 sufciently removed fromA the member I0 so that both valve bodies I8 and 2| will have relative movement with respect to each other and to the said member I0 in the operation of the valve assembly A for the perfect opening and closing thereof.

Disposed about the sleeves l1 and 20 and the bolt I6 is a convoluted spring 3| which is seated against the body 2| and also against an abutment washer 32 at the headed end of the bolt I6. This spring normally holds thevalve bodies I8 and 2| seated or the valve assembly in a closed condition. However, the spring 3| may be entirelydispensed with and in this-arrangement the valve bodies i8 and 2| will gravitate to closing positions.

The baille and groove formations create a cushioning effect during the closing operation of the valve assembly A, and there will be no noisy slapping of the valve bodies I8 and 2| during the working of said assembly.

The presence of the baliles and grooves inthe peculiar formation thereof assures a perfect seating of the valve bodies I8 and 2|, respectively, throughout the entire working life of the valve assembly. i

The valve assembly A constructed as hereinbefore set forth is leak-proof. There is no liability of either valve body I8 and 2| hanging slightly open when present with the ribs and grooves as before explained in that such bodies will settle to seating positions. There can be no leakage in the valve assembly A around the sleeves or bolt, by the arrangementl of the baffles and grooves. The baflies and grooves eect the righting of the valve bodies when seating and guide the same to seating positions.

What is claimed ist l A valve of the kind described, comprising a ring member including a central perforated hub,

an annulus concentric thereto and radial spokes joining the hub and annulus for effecting iiuid passages therebetween, superposed separable disks of` approximately equal areas and thicknesses disengageably contacting each other, the lowermost of said disks and said ring member having contacting faces, said lowermost disk being provided with through passages opening into recesses in the opposite faces of said lowermost disk, a headed bolt removably tting the perfodisk, and rigid knife edge ribs on said disks con-v centrically arranged with respect to each other for intertting respectively with corresponding grooves in the lower disk and in the ring member, for encirclement of the hub perforation and the said passages' in the ring member to avoid'leakage about the same, said contacting faces of the disks and the ring member together with the ribs being effective as a positive seal therebetween.
